Thinking on new rewards for 10 or 20$ Patrons (Patreon)

Apparently raffles aren't allowed on Patreon, and i can't do 200 animations for 200 people, so i was thinking what i can do to have the chance of rewarding the 20 or 10 bucks patrons.

What about polls?..., i can release a few polls asking how the next animation is going to be, poses, characters, maps, etc..., is like doing an commission for everyone.

What you think?

Of course those patrons can access to the animation way before everyone else.
